SHEET-METAL WHEEL.

pensive in construction, which is strong, durable, and wherein a desirable degree of resiliency in the wheel structure is secured.

Other objects ofthe invention will appear more fully hereinafter. v

The invention consists substantially in the 1 construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set forth as shown in the'accompanying drawings, and finally pointed out in the appended claims.

In the drawings,-

Fig. 8 is a view in side elevation of a reinforcing flange ring for the felly structure of wheel shown in Fig. 5.

Fig. 9 is an edge view of thering shown in Fig. 8.

The same part is designated by the same reference numeral: wherever it occurs throughout the several views.

Reference numeral 10 designates the wheel hub. This may be of any desired structure or formation, and while I have shown a hub structure as applied toa floating axle type, I-

, wish it to be understood that my invention is not to be restricted or limited in this respect.

so In the particular type shown 12 is the driving member mounted on the shaft 13 and rotat-' ing therewith and with the wheel. 14 is the axle cap. In practice the hub 10 and driving member 12 are constructed with annular flanges 15, 16, respectively, which are bolted or otherwise secured together and to the Application filed a ril 15, 1919. Serial No. 290,208.

also suitably bolted or otherwise secured to the wheel and to the hub sleeve and driving member 12 is brake drum 17. v p

4 The parts so far described may be of any suitable or well known structure, and in the details thereof form no part of my present invention. i

The sheet metal wheel embodying my in-v vention includes the disks 18, 19, suitably stamped out and dished, and each formed with a central flanged opening. For example, the dis 18 is formed with a central flange while the disk 19 is likewise provided with the central flange 21. 'The'flange 20 of disk 18 extends outwardly and-fits annularly upon the hub sleeve 10. The flange 21 of disk 19 extends inwardly and fits annularly upon the flange 20. These flanged central portions of the disks are received in the channel formed between the hub sleeve flange 15 and the opposed surface of the brake band drum 17. Disposed between the disks 18, 19, and surrounding the flanges 20, 21, thereof, is a ring wheel. Mounted upon the hub sleeve 10 and shaped wooden block 22 which performs the function of a spacer block for the disks and at the same time affords a desirable degree of resiliency or yielding of the wheel structure in use avoiding that rigidity which an allmetal structure ordinarily presents. The wooden spacer block 22 occupies the space be tween the opposed surfaces of the disks 18, 19, adjacent to the central portions of said disks and radially from the spacer block the disks are brought into contact and secured together at their peripheral edges.

In order to secure thedesired reinforcement for the disk 18 and a keeper to retain the wooden block 22 in place and to prevent the latter from becoming split or injured in use a reinforcingmetal ring member 23 is applied to the exterior surface of the wooden ring 22, said reinforcing ring if desired, being formed or stamped with lugs or flanges 24 which are riveted or otherwise secured to the exterior face of disk 18. This reinforcing metal ring 23 not only serves to properly re-. tain the wooden spacer block, in place and prevent the same from splitting but also reinforces and stiifens the disk 18, while at the same time permittinga desirable degree of resiliency thereof. It will be observed that the wheel disk 19 at a point intermediate its central hub open- 7 ing and its main body portion, is formed-with an outwardly curved portion which merges Elli to materially strengthen and stiffen the disk jpartlcularly in the region of its hub where 5 the greatest load'strain occurs when the wheel is in use, j v

3 In order to still further stifien the disks 18, 19, I prefer to stamp thereincircular grooves in the contacting surfaces thereof,

These grooves are formed near the eripheral portions of the diskswhich lie. atwise against each other.

Any suitable or convenient rim structure or tire retaining device may be employed connection with a stamped metal wheel embodyingmy invention. In the arrangement shown in Fig. 2, 26v designates an angle shaped tire retaining rim section, the angle of which fits over the peripheral edges of the sheets or disks 18, 19'. A securing bolt 27, see Fig. 7 is passed through the two disks 18, 19, and the angle flange 28 of the rim member 26, A cooperating rim member 29 is also 'detachably retained in place by the nut 30 on the bolt 27. In this form of my invention the bolt 27 is provided with an elongated head 31 which fits flatwise against the inner face or surface of the disk-stamping 18 and is riveted or otherwise permanently secured thereto. By simpl removing the nuts '30 from the bolts 27 t e tire retaining rim sections 29, 26, may be removed,or.the members or lugs 29 may be removed to permit the removal of the tire. 1

In thej'arrangementshown in Figs. '5 and 6 a slightly modified arrangement is shown wherein .two stifiening rings or bands 32, 33, having if desired, the lugs 34 stamped therein, are employed in place of the stifiening and retaining band or ring 23. above described with reference to the structure shown in Figs.

2, 3 and 4, The retaining and stiffening band or ring 33 has-its lugs 34 riveted or otherwise secured to the disk 18, while the band or re-' taining ring 32 has its lugs 34-riveted or otherwise secured to the disk 19, the two rings,

.or hands 32, 33 being nested or telescoped the one upon the other. I have also shown a modified arrangement shown in-Fig. 5. In this instance the peripheral edge portions of .the disks 18; 19 them-' selves constitute one member of the tire re-.

tainingstructure, said'ed es being bentlatorally or into angular re ation with r .tothe body portions of the disks 18, 19, and

the. extremeperipheraledge 35 of disk 19 being bent or folded over the; extreme edge 3601: the disk 18, the two edgesbeing deflected upwardly tojforin a bearing for the tire ,rim 37 m cooperation with retaining lugs 38. In

,order to secure greater strength and sturdiness of the tire retaining structure an angle Cl ring member 39 is lPPliedat the angle which grooves nest the one into the other.

- transverse vertical plane through the hub.

-With this arrangement it will be observed 7 .that the flatwise contacting radial portions 'of the disks are to'one side of the central .;sta'mped wheels, .which, while strengthened by the reinforcing'rings .or hands of tire retaining devices in the structure espect only by the use of the wooden spacing channels 25, the latter not only the weight strains ture of mvf inventionand constructiol m 1 ne therewith "let I formed'by bending the peripheral edge porwhich nuts 41am applied. These bolts may be headed and Welded into seats formed to receive the heads in the stifien ing ring 39. 2 In the construction shown in Fig. 5, the disks 18, 19, are formed of suitable metal stampings, said disks being'flanged at their central openings, said flanges being bent or deflected laterally towards each other to form a central 0 lindrical portion 50 which constitutes a hu portion whichfits on thewheel hub 10. Th'ewooden spacer block 22in this instance fits the channel formed bybending the disks '18, 19 radially from the hub -flange portion 50.

It will be observed that not only does the wooden'sp'acing block or ring serve the fumes tion of a spacer. for the hub portions of'disks 1 18, 19, but it also serves to deaden the sound and to absorb and take up to a desirable degree the shock of impact over rough broads, thereby securing a desirable degree of res iliency in the wheel. v i 1 It will also be observed, see particularly Fig. 5, that the portions of the disks which in this case towards the left. from the central '1 lineof'the tire whenapplied. :l'he. purpose of this arrangement and construction-is. to 11 avoid rigidity resulting .from a strictly radial r elation of the disks, and tosecure a desirable degree of resiliency in the wheel i structure, Jpermittin'git to absorb'shock, jar and vibrationswhen'tlie wheel is in use.- j From the foregoingdescription it be seen that I provide an exceedingly simpl .ruggeid, durable and inexpensive-structure o V b 11 still afford a desirable degree of yield to ab: sorb the shocks andvibrations 'due to the op-" erationof vehicles equipped with such wheels 1 1 over rough places'in t e roadway. -The' resiliency 1n the whe'elis contributed tralggfi' ut also by the retain' iandfstlfi rings or hands 23, 32, 33,]
